15 Claims. (Cl. 200-1155) This invention relates to new and useful improvements in fused electric connectors and receptacles.

More specifically, the present invention proposes certain improvements in that type of fused electric receptacles which removably encloses a pair of cartridge type fuses for providing coniplete protection for the electric appliance or device with which it is connected and which will completely eliminate the danger of fire resulting from faulty electrical equipment.

As a further object, it is the primary purpose of the present invention to construct the fused electric receptacle so that it will have a pair of lug-in bars extended from its one end for insertion into a conventional electric outlet receptacle with a pair of openings at its other end associated with a pair of conductor members in a manner so that when the plug-in bars of a conventional plug attached to the cord of an electric appliance or device are inserted into the openings good electrical contact will be made with the conductor members to supply the current required to operate the appliance or device and at the same time the contained fuses will protect the appliance or device.

Another object of the present invention proposes constructing the fused electric receptacle to include a hollow body formed with an internal rib which divides oif spaced channels within the body into which cartridge fuses are inserted in a manner to make electrical contact with spring clips mounted within the channels at the ends thereof.

As a further object, the present invention proposes openings in the one end. of the body in alignment with the channels through which the fuses can be passed into electrical contact with the clips and holes in the other end of the body in alignment with the channels in a manner so that an elongated pusher member can be inserted through the holes for applying pressure to the fuses pushing them from the clips and out of the hollow body through the openings.

The present invention further proposes forming the clips at the end of the channels adjacent the holes with conductor strips projected into recesses formed in the rib inwardof the respective clips in a manner sothat when the plug-in bars of the conventional plug are inserted into the hollow body they will make electrical contact with said conductor strips.

As a still further object, the present invention proposes providing means within the hollow body for causing the conductor strips to be continually resiliently turned in a direction to bear rigidly against the plug-in bars of the plug in amanner to insure good electrical contact between. the conductor strips and the plug-in bars of the plug.

Still another object of the present invention proposes arranging the turning. means in such a manner that the act of turning the conductor strips to make good electrical contact with the plug-in bars of the plug will also cause the respective clips to be held in concentric alignment within the respective chanels to always be in position to receive the ends of the fuses when being inserted into position within the hollow body.

A further object of the present invention proposes constructing fused receptacles in several dififerent ways to be used between the outlet receptacles and the plugs of electrical appliances or devices or to be mounted on the ends of extension cords in a manner .to provide complete protection for the electrical appliances or devices which draw their electricity from the extension cords.

For further comprehension of the invention, and of the objects. and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 20 is an inside elevational view of one of the halves of the receptacle body of the form of the invention shown in Figs. 18 and 19.

The fused receptacle, according to the first form of the present invention illustrated in Figs. 1 to 8, includes a hollow body 343. The hollow body 38 is comprised of opposed halves molded of any suitable dielectric material such as hard rubber. However, the body halves 36* are preferably molded of one of the synthetic resinous materials having good dielectric properties. Each of the body halves 36 is semi-elliptical in cross-section so that the body 30, when the halves are brought together, will be elliptical in cross-section, as can be best seen from Fig. 1. The ends of each of the body halves are closed by thin integral walls 3| and 32 which have meeting edges when the body halves are brought together.

Internally, the body halves 33 are formed with narrow ribs 33 which are in alignment with each other and which extend at right angles to the end walls 3| and 32. The ribs 33 are located mid-way between the sides of the body halves 3!! and divide oif spaced channels 34 for a purpose which will be explained as this specification proceeds. Each of the body halves 30 has an aperture 35 extended through its rib 33. When the body halves 35 are properly brought together, as shown in Fig. 4, the apertures 35 will be aligned for the passage of a nut and bolt assembly 34 which holds the body halves together as a unit. The outer ends of the apertures 35 are counter sunk to receive the head and the nut of the nut and bolt assembly so that the outer faces of the body halves remain flush.

The outer faces of the body halves 33 removed from the apertures 35, are formed with inwardly sloped cavities 31 bounded on their deepest sides by outwardly directed ridges 38. The cavities 3'! and the ridges 33 combine to provide convenient finger grips for pulling the fused receptacle out of a conventional electric outlet receptacle, as will become clear as this specification proceeds.

The channels 34, previously referred to, are in alignment when the body halves 30* are brought together and house cartridge type fuses 39. As is generally known in the art, the amperage of the fuses 39 used in the receptacle will be governed by the wattage of the electrical appliance or device with which the receptacle is used. Positioned in the ends of the channels adjacent the end walls 3|, there is a pair of like clips 43 which are engaged about the adjacent ends of the fuses 39. Positioned in the ends of the channels 34 adjacent the end walls 32, there is another pair of like clips 4| which are engaged about the other ends of the fuses 39. The clips 40 and 4| are resilient in construction so as to tightly grip the ends of the fuses and make good electrical contact therewith.

The end walls 32, in alignment with the ends of the channels '34, are formed With em -c cular notches 42. When the body halves 33 are brought together, the notches 42 combine to form circular openings of a diameter to pass the fuses 39. The fuses 39 are inserted into the body through the circular openings formed by the notches 42 and the mere act of pushing the fuses 39 into position in the channels 34 causes them to be mounted in electrical contact with the clips 43 and 4|.

The end walls 3| at the other ends of the channels 34, are formed with smaller semi-circular notches 43 which combine, when the body halves 30* ar brought together, to form small circular holes. The small circular holes are provided so that the end of a rod-like ejector, illustrated by the dot and dash lines 44 in Fig. 2, can be inserted therethrough to be used for pushing burnt out fuses 39 from the body 35.1 through the circular openings formed by the notches 42. In Fig. 2, one of the fuses 39 is illustrated in a partially ejected position. A small nail, a bobby pin, the tine of a fork or any other similar article can be used as a rod-like ejector. On the other hand, the receptacle could be supplied with an elongated wooden stick which could b used as a rod-like ejector.

The clips 4| are bent from strips of resilient conductive metallic material and have intermediate portions engaged about elongated plug-in bars 45. The plug-in bars 45 are shaped from rigid conductive metallic material and have end portions projected from the end walls 32 of the hollow body 30 for insertion into the receiving openings of a conventional electric outlet receptacle. The intermediate portions of the clips 4| are secured to the inner ends of the plug-in bars 45 by spot welding, riveting or in any other similar manner. The ribs 33, in lateral alignment with the clips 4| and inward thereof, are formed with aligned recesses 46 into which the intermediate portions of the clips 4| are extended. The intermediate portions of the clips 4| have a snug fit within the recesses 46, see Fig. 2, so as to retain the plug-in bars 45 against possible longitudinal movement with relation to the body 35.

The intermediate portions of the plug-in bars 45 pass through aligned notches 41 formed in the end walls 32. The inner ends of the plug-in bars 45 which extend beyond the intermediate portions of the clips 4| are fitted into complementary notches 48 formed in the ribs 33. Engagement of the plug-in bars 45 with the notches 41 and 48 in addition to retaining the bars against possible lateral displacement, also functions to retain the clips 4| concentrically in position within the channels 34 to receive the fuses 39.

The clips 40 which are fashioned from a blank similar to that shown in Fig. 6, are bent to the desired shape from a single piece of flexible conductive metallic material having substantially the shape of a cross. The arms of the crossshaped pieces of material are bent to form the clips 40 which are circular in cross-section. One end of the bar portion of each of the crossshaped pieces of material forms a tail portion 49 and has its free end bent into a semi-circular anchor portion 50 faced with its open side toward the respective fuse 39. The other end of the bar portion of each of the cross-shaped pieces of material is doubled back upon itself forming a con-.

ductive strip portion 5|. As best shown in Figs. 2 and 5, the conductive strip portions 5| are angled away from the adjacent faces of the tail portions 49.

The ribs 33 inward of the channels 34 and the respective clips 40 are formed with elongated recesses 52. which are spaced from the channels 34 by intermediate walls 53. The walls 53 in alignment with the clips 40' are formed with cutouts 54 through which the intermediate portions of the clips 40 pass so that the clips 45 can be located within the channels 34 with the tail portions 49 and the conductive strip portions 5| located within the recesses 52. The ends of the walls 53 remote from the end walls 3| are formed with inwardly extended semi-circular lugs 55 about which the semi-circular anchor portions 50 of the tail portions 49 are engaged, as best shown in Fig. 2. The ribs 33 are formed with small projections 56 which abut the semi-circular anchor portions 50 retaining them rotatively in engagement with the semi-circular lugs 55.

The end walls 3| of the hollow body 30 are formed with notches 51 which continue from the outer ends of the recesses 52. The notches 51, when the body halves 30* are brought together form passages through which the ends of the plug-in bars of a conventional plug can be passed into the recesses 52 to make electrical contact with the conductive strip portions 5|. The conventional plug referred to is that type of plug which. is commonly mounted on the end of an electric. cord of conventional electrical appliances or devices; such as clocks, toasters, radios, television sets, irons, and the like. Thus, it will now be appreciated that the receptacle of the present invention is to be inserted between the conventional outlet receptacle for electric current and the plug of common electrical appliances so that the fuses mounted in the receptacle will function to provide complete protection for the electrical appliance or device with which it is connected.

Means is provided for turning the semi-circular anchor portions 55 about the semi-circular lugs 55 for holding the strips portions 5| in position to make good electrical contact with the plug-in bars of the inserted plug and for holding the clips 40 concentrically in position within the passages 34 to receive the fuses 39. The turning means comprises a transversely extended flexible anchor plate 58' fitted into opposed complementary grooves 59 formed in the adjacent faces of the body halves 30 The grooves 59 are located at the ends of the recesses 52 so that the one face of the anchor plate 58 bears against the. free ends of the semi-circular anchor portions 55. When the anchor portions 50 are not engaged by the anchor plate 58, they have a natural bias, as shown in Fig. 5, so that their free ends stand away from the lugs 55. However, when the anchor plate 58 is in position it tends to compress the ends of the semi-circular anchor portions 55 against the lugs 55 causing the anchor portions 55 to turn about the lugs 55. As a result, the clips 45 and the strips portions 5|, as viewed in Fig. 2, will be moved as a unit with the right hand ones turning in a counterclockwise direction and the left hand ones turning a clockwise direction. Such movement will cause the strip portion- 5| to bear with good electrical contact against the adjacent faces of the inserted plug-in bars and maintain the clips 40 concentrically in position within the channels 34.

The anchor plate 53 is stamped from a thin sheet of dielectric material which preferably is fiber or the like material. It is also appreciated, that when the anchor plate 58 is in position, as shown in Fig, 4, it assists in retaining the body halves 30 against pivoting about the nut and bolt assembly 36.

From the foregoing; description, it is apparent that the present invention provides a convenient fused receptacle which can be used for protecting any type of electrical appliance or device having a plug for insertion into a conventional outlet receptacle. The fused receptacle of the present invention is characterized by the fact that it may be quickly disconnected from the appliance or device with which it is being used and connected to another without using any tools or requiring any skill. A feature of the present construction resides in the fact that the ends walls 3| and 32 of the body halves 3|] are especially thin with the overall length of the body 30 being not much greater than the length of the contained fuses 39' so that little movement of the fuses is required for removing the same or inserting new ones.

In the modification of the invention shown in Figs. 9 to 1-1, the construction of the fused receptacle is characterized by the fact that the tail portions 49' of the clips 4|] are of straight elongated formation. Those tai'l portions 49' are extended flush along the adjacent faces of the walls 53 and have their free ends fitted snugly into notches 60 formed in the rib 33 at the adjacent ends of the recess 52".

In all other respects, the form of the invention shown in Figs. 9 to 11 is similar to that previously described and like reference numerals are used to identify like parts.

The modification of the invention shown in Figs. 12 to 14, is characterized by the fact that the fused receptacle is designed to receive the plug-in bars of an electric cord or cords at both of its ends. The fuses 3."! are engaged at their ends by clips 45" similar in construction to the clips referred to in connection with the description of the form of the invention shown in Figs. 9 to 11. At each end, the body halves 39 are formed with recesses 52 which house the tail portions 49 and the conductive strip portions 5| of the clips 40. Each of the ends walls 3| and 32' is formed with the aligned. notches which extend from the outer end-s of the recesses 52 to admit the plug-in bars of the plugs.

The fused receptacle of Figs. 12 to 14 is constructed to be inserted between the adjacent ends of a severed cord of an electric appliance or device. Conventional push-in plugs are mounted on the severed ends of the cord for insertion into the fused receptacle from opposite ends thereof for providing protection for the appliance or device.

In all other respects, the form of the inventi on shown in Figs. 12' to 14 is similar to that de scribed in connection with Figs. 9 to 11 and like reference numerals identify like parts.

Referring now to the modification of invention shown in Figs. 15 tov 17, the clips 42 on opposite ends of the fuses 39 adjacent the end wall 3| and 32* are formed with metallic extensions-101 The extensions 10 are projected into complementary recesses H. formed in the adjacent faces of the ribs 33 Each of the extensions Hi carries attaching screw 72.

The body halves 36 are alike in construction differing only in the fact that the one half is formed with a centrally located hole 73 through which the end of an electric cord 1 3 is projected into the hollow body 35.. Extended in opposite directions from the hole: 3 to th recesses H,

I the adjacent facesof the.- ribs 33 are formed with passageways 15 through which the individual leads of the cord 73 are extended to the respective extensions 18. The ends of the leads of the cord 13 are attached to the extensions 13 by means of the screws 12.

The body halves 30 in this form of the invention are secured together by means of two sets of nut and bolt assemblies 36 projected through complementary aligned apertures 35 extended through the ribs 33 outward of the recesses TH.

In all other respects, the form of the invention shown in Figs. 15 to 17 is also similar to that described in connection with Figs. 9 to 11 and like reference numerals identify like parts.

In the modification of the invention. shown in Figs. 18 to 20, the clips lll are located adjacent the end wall 32' of the hollow body 30. ihe clips. M are located adjacent the end wall fil of the hollow body and are constructed to include extensions 80 positioned within complementary aligned recesses 8| formed in the adjacent faces of the ribs 33*. The extensions 86 are each provided with a single attaching screw 32.

The halves of the body 30 are alike in formation and the end walls 3|", between the notches 43, are formed with aligned passages 83 through which a cord 84 enters the hollow body 30. Within the ribs 33", the passages 83 continue into aligned branch passages 85 which communicate with the recesses 8 I. The individual leads of the cord 84 are extended through the branch passages 85 and into the recesses 81 where they are connected to the extensions 80 by means of the attaching screws 82.

Again, the form of the invention shown in Figs. 18 to 20 is similar to that described in connection with Figs. 9 to 11 and like reference nu merals are used for identifying like parts.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
